tex_demo.py

#!/usr/bin/env python"""You can use TeX to render all of your matplotlib text if the rcparameter text.usetex is set. This works currently on the agg and psbackends, and requires that you have tex and the other dependenciesdescribed at http://matplotlib.sf.net/matplotlib.texmanager.htmlproperly installed on your system. The first time you run a scriptyou will see a lot of output from tex and associated tools. The nexttime, the run may be silent, as a lot of the information is cached in~/.tex.cache"""from matplotlib import rc
